Wails v3 正式发布：用 Go 写桌面应用，体积仅 12MB，性能飙升 40%！

This paper presents the state of the art of Adaptive Cruise Control (ACC) and Stop and Go systems as well as Intelligent Transportation Systems enhanced with inter vehicle communication. The sensors used in these systems and the level of their current technology are introduced. Simulators related to ACC and Stop and Go (S&G) systems are also surveyed and the MEKAR simulator is presented. Finally, future trends of ACC and Stop and Go systems and their advantages are emphasized.

采用液压同步提升技术吊装转炉炉壳，将炉壳分上部炉壳、中部炉壳和下部炉壳三部分拆装，其中旧上部、中部炉壳采用整体拆除吊离后再分体，新上部、中部炉壳组对后再整体吊装。采用液压同步提升技术，可有效解决受重量和现场空间限制，无法使用行车、吊机等常规起吊设备吊装转炉炉壳的问题。

I comment on the above paper(s) discussing the issue of non-ultralocality for Ginsparg-Wilson fermionic actions. The purpose of this note is to point out that the new claim in "v3" (Feb 24, 2000), alleging the proof for "all Ginsparg-Wilson fermions", might not be substantiated. The remarkable evolution of versions of this paper is put in context with the literature existing at the time of their appearance.
